Abstract
A fibre optic cable () comprises retractable fibre units () extending in parallel with one another within an extruded polymer tube (). The fibre units are free to slide in the tube such that a selected fibre unit () can be accessed and re-directed by forming an opening in a wall of the tube () and withdrawing the selected fibre unit through the opening (). Each fibre unit comprises two or more optical fibres () embedded in a solid resin material () to form a coated fibre bundle and an extruded polymer sheath (). The fibre optic cable is manufactured by feeding the fibre units through an extrusion head () by which the extruded tube () is formed. The sheath () of each fibre unit is primarily polyethylene. A lining () of the extruded polymer tube is formed by polymer other than polyethylene, for example polypropylene.
